Gemma is a sister-in-training. Her twin brother Go Mi Nam successfully auditions for the musical band A.N.JELL but is forced to leave for the United States to correct a botched plastic surgery. Mi Nyu is approached by Mi Nam's manager to pose as Mi Nam while he recovers. She is against it at first but agrees in order to fulfill her dream of finding their mother.

Now, posing as Mi Nam, Mi Nyu enters the group A.N.JELL and meets its members: Hwang Tae Kyung, Kang Shin Woo and Jeremy. Tae Kyung and Mi Nam have a rough start as band members. In the very first episode, Kang Shin Woo discovers that Mi Nam is a girl, but he keeps quiet because he is curious about what might happen. He discreetly helps her keep the secret and nobody realizes that he knows her true gender. Soon after that, due to an incident, Tae Kyung also discovers that Mi Nam is a girl, and confronts her about it.

He actively takes on the responsibility of protecting her real identity from others (partly due to Mi Nam's manager begging him), which brings him and Mi Nam closer together. Slowly all the band members - Shin Woo, Tae Kyung and Jeremy - fall in love with Mi Nam(although Jeremy tries hard to deny it because he thinks Mi Nam is a guy). Eventually, Mi Nam admits her gender to the entire band, and they all help keep her identity secret until her brother arrives from the USA.

The series ends when Mi Nam, as her real girl self, finally gets together with Tae Kyung.Main Character Description
